SPRING-WINDING DEVICE.

Application filed January it), 1923.

To all 10 item it may concern Be it known that 1,1IENRY l Lnronrnnn, acitizen of the United States, residing at Biddeford, in the county ofYork and State of Maine, have invented certain new and usefulImprovements in Spring-Winding Devices, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to spring Winding devices, and has for its objectto provide a device of this character capable of being supported in avise for easily and quickly windmg a spring. I

It is another object of the invention to provide a device of thischaracter wherein springs of various widths may be evenly woundand'readily removed.

It is a further object of the invention to provide a device of thischaracter wherein the means for guiding and guarding the spring isadjustable according to the width of the spring.

It is a still further object of the invention to provide a device ofthis character wherein means are provided for holding the spring woundto permit the same to be removed from the winding device.

With these and other objects in view, the

invention consist-sin the improved construction and arrangement of partsto be hereinafter more particularly described, fully claimed andillustrated in the accompanying drawings, in which Y Figure 1 is a viewin elevation of a spring winder constructed in accordance with anembodiment of the invention;

Figure 2 is a view in elevation with the guard plate extended to oneside;

Figure 3 is a transverse sectional view; and

Figure a is a view of a spring showing the clip applied.

Referring to the drawings, 5 designates a supporting plate having ashaft 6 rotatably mounted therein, the shaft being provided with aratchet wheel 7. Secured to the supporting plate is a frame 8 havingspacing blocks 9 projecting therefrom and adapted to engage the plate 5.This frame substantially coacts with the plate to provide a compartmentfor the reception of a pawl 10, a spring 11 being connected to the frameand the pawl for urging the pawl into engagement with the ratchet.

Projecting from one edge of the plate is Serial No. 611,744.

an extension 12 adapted to be disposed between the jaws of a vise orlike holding means whereby the supporting plate may be supported inconvenient position for winding the spring. I Secured to one end of theshaft 6 is an operating handle 13, said handle projecting from the sideof the plate remote from the frame 8. Projecting from the plate adjacentthe frame is shaft 14. A guard plate 15 is carried by the shaft, saidguard plate having a slot 16 which extends to the central portionthereof. The guard plate is also provided with an extension 17 having acollar 18 adapted to receive the shaft Secured to the supporting plateadjacent the shaft 14: is a keeper member 19, said keeper member havinga plurality of recesses 20 adapted to receive the eX- tension of theguard plate 15, so as to hold said plate in various adjusted positionson the shaft 14..

Carried by the plate 15 adjacent the shaft 14 is a supporting shaft 21adapted to receive one end of a spring A, the opposite end of the springbeing connected to the shaft 6. Projecting from the, plate adjacent theshaft 21 is a guard shaft 22, adapted to prevent movement of the springbeyond the opposite edge of the supporting plate. The shaft 22 isprovided with a lug 22 adapted for engagement in the slots of springends so that springs having this type of end may he held againstmovement. In the operation of the device, when it is desired to, wind aspringthe loop of the spring is engaged with the shaft 21 and the innerend of the spring secured to the shaft 6. The handle member is thenrotated by the operator so as to cause the spring to be wound to thepoint desired during which time the pawl 10 engages the ratchet wheel inthe usual manner to control the movement of the shaft, .ffter the springhas been positioned on the shaft the guard plate 15 is rotated so as topermit the end of the shaft 6 to enter the slot 16, the guard platebeing moved longitudinally of the shaft 14: according to the thicknessof the spring. In this way the coils of the spring are disposed in thesame plane and properly wound. After the spring has been wound to theextent desired a Cl-Shaped clip 23 is engaged with the wound portions ofthe spring, the spring being wound to such a point that it is smaller indiameter than the clip. After the clip is applied the spring is slightlyunwound to permit the same to bind within the clip, whereupon the guardplate 15 may be removed and the spring disengaged from the shaft 6.

From the foregoing it will be readily seen that this invention providesa novel form of spring winding device capable of winding a spring of anywidth and wherein the spring may be readily removed from the deviceafter winding without danger of un- Winding and in such a position thatit may be readily inserted in the mechanism of a clock in view of the'novel C-shaped clip. In addition to this the extension 12 of thesupport permits the device to be secured in a vise or like holdingmember without re quiring any special holding means.

What is claimed is 1. A spring winding device comprising a supportprovided with means for engagement within a vise to efi'ectholding, ashaft journaled through said support and having a crank handle, a diskon the shaftspaced from the support and defining a compartinent, aratchet on said shaft within said compartment, a pawl within saidcompartment oo-operating with said ratchet and having an end projectingbeyond the support to facilitate manipulation, guard plate rotatablymounted on said support and having a slot for the reception of saidshaft, and means on the support for holding the guard plate ,in anadjusted position.

2. A spring winding device comprising a support, a shaft rotatablymounted therein and provided with a handle, a ratchet wheel on theshaft, a pawl pivoted on the support and co-operating with said ratchet,a mem-, 'ber projecting outwardly from the face of the support, a guardplate rotatably mount ed on said member and swingable to overlie aspring wound upon the shaft, the guard plate having a slot accommodatingsaid shaft, and means for holding the guard plate a selected distancefrom the support.

3. A spring winding device comprising a support, an extension carried bythe support and adapted to be engaged with hold-' ing means, a shaftrotatably mounted on the support and extending at right angles thereto,a ratchet wheel carried by the shaft, a frame surrounding said shaft anddisposed in spaced relation to the support and extending over theratchet' wheel, said frame coact-ing with the support to provide acompartment for a pawl, a stationary shaft carried by the support, aguard plate 'slidably mounted on the stationary shaft,

said guard plate being. movable over the support and having a slot forthe reception of the rotatable shaft, a keeper member disposed adjacentthe shaft of the guard spring engaged thereon, a shaft journaled throughthe support and equipped with a handle and a lug adapted for engagementwith the inner end of the spring, a ratchet onflsaid shaft, a pawlpivoted on the support and coacting with the ratchet, a sta tionaryshaft projecting from the support in p'arallelrelation to said'rotaryshaft, a guard plate rotatably mounted on saidstationary shaft andslotted for the accommodation of the rotary shaft, the guard plate beingswingable to extend across the spring, and a bar projecting from thesupport adjacent the stationary shaft and formed with a pluralityof'notches within a selected one of which the guardplate may be engaged.In testimony whereof I hereunto afiix my signature.
